The trick is simple:
Open the player's tray, put a Region One disc on the tray, press the 0, 1, 2
and 3 buttons on the remote control, and finally press Play on the remote. That
closes the tray and from this point on the player will accept DVDs from any
of the six main regions.

You can also press pause on an Aiwa stereo remote whilst pointing at unit. You
will see a maintenance screen. Set the region, and off you go. This works on
my Wharfedale.

Readers Chris Dennis and Tom note that to convert the player back to
Region Two only, the procedure is: open the tray, place a Region Two disc on
the tray, press the Return button on the remote and finally press the remote's
Play button.
